mtd: rawnand: Create a legacy struct and move ->IO_ADDR_{R, W} there
We regularly have new NAND controller drivers that are making use of fields/hooks that we want to get rid of but can't because of all the legacy drivers that we might break if we do. So, instead of removing those fields/hooks, let's move them to a sub-struct which is clearly documented as deprecated. We start with the ->IO_ADDR_{R,W] fields.
